title: Retroperitoneal abscess presenting as emphysema of the thigh.
abstract: Leg pain may be a presenting symptom of intra-abdominal disease. I report a case of subcutaneous emphysema of the thigh that was a complication of diverticular perforation and abscess formation. Healthy leg muscle was found at operation, showing that myonecrosis need not necessarily be present even with finding of extensive gas accumulation.
